IELTS Reading: Actual Test Vol 6 - Test 4

A

Although we lack accurate statistics about child mortality in the pre-industrial period, we do have evidence that in the 1660s, the mortality rate for children who died within 14 days of birth was as much as 30 per cent. Nearly all families suffered some premature death. Since all parents expected to bury some of their children, they found it difficult to invest in their newborn children. Moreover, to protect themselves from the emotional consequences of children’s death, parents avoided making any emotional commitment to an infant. It is no wonder that we find mothers leave their babies in gutters or refer to the death in the same paragraph with reference to pickles.

The 18th century witnessed the transformation from an agrarian economy to an industrial one, one of the vital social changes taking place in the Western world. An increasing number of people moved from their villages and small towns to big cities where life was quite different. Social supports which had previously existed in smaller communities were replaced by ruthless problems such as poverty, crime, substandard housing and disease. Due to the need for additional income to support the family, young children from the poorest families were forced into early employment and thus their childhood became painfully short. Children as young as 7 might be required to work full-time, subjected to unpleasant and unhealthy circumstances, from factories to prostitution. Although such a role has disappeared in most wealthy countries, the practice of childhood employment still remains a staple in underdeveloped countries and rarely disappeared entirely.

C

The lives of children underwent a drastic change during the 1800s in the United States. Previously, children from both rural and urban families were expected to participate in everyday labour due to the bulk of manual hard working. Nevertheless, thanks to the technological advances of the mid-1800s, coupled with the rise of the middle class and redefinition of roles of family members, work and home became less synonymous over time. People began to purchase toys and books for their children. When the country depended more upon machines, children in rural and urban areas, were less likely to be required to work at home. Beginning from the Industrial Revolution and rising slowly over the course of the 19th century, this trend increased exponentially after civil war. John Locke, one of the most influential writers of his period, created the first clear and comprehensive statement of the ‘environmental position’ that family education determines a child’s life, and via this, he became the father of modem learning theory. During the colonial period, his teachings about child care gained a lot of recognition in America.

According to Jean Jacques Rousseau, who lived in an era of the American and French Revolution, people were ‘noble savages’ in the original state of nature, meaning they are innocent, free and uncorrupted. In 1762, Rousseau wrote a famous novel Emile to convey his educational philosophy through a story of a boy’s education from infancy to adult-hood. This work was based on his extensive observation of children and adolescents, their individuality, his developmental theory and on the memories of his own childhood. He contrasts children with adults and describes their age-specific characteristics in terms of historical perspective and developmental psychology. Johan Heinrich Pestalozzi, living during the early stages of the Industrial Revolution, sought to develop schools to nurture children’s all-round development. He agreed with Rousseau that humans are naturally good but were spoiled by a corrupt society. His approach to teaching consists of the general and special methods, and his theory was based upon establishing an emotionally healthy homelike learning environment, which had to be in place before more specific instructions occurred.

E

One of the best-documented cases of Pestalozzi’s theory concerned a so-called feral child named Victor, who was captured in a small town in the south of France in 1800. Prepubescent, mute, naked, and perhaps 11 or 12 years old, Victor had been seen foraging for food in the gardens of the locals in the area and sometimes accepted people’s direct offers of food before his final capture. Eventually, he was brought to Paris and expected to answer some profound questions about the nature of human, but that goal was quashed very soon. A young physician Jean Marc Gaspard Itard was optimistic about the future of Victor and initiated a five-year education plan to civilise him and teach him to speak. With a subsidy from the government, Itard recruited a local woman Madame Guerin to assist him to provide a semblance of a home for Victor, and he spent an enormous amount of time and effort working with Victor. Itard’s goal to teach Victor the basics of speech could never be fully achieved, but Victor had learnt some elementary forms of communication.

Although other educators were beginning to recognise the simple truth embedded in Rousseau’s philosophy, it is not enough to identify the stages of children’s development alone. There must be certain education which had to be geared towards those stages. One of the early examples was the invention of kindergarten, which was a word and a movement created by a German-born educator, Friedrich Froebel in 1840. Froebel placed a high value on the importance of play in children’s learning. His invention would spread around the world eventually in a verity of forms. Froebel’s ideas were inspired through his cooperation with Johann Heinrich Pestalozzi. Froebel didn’t introduce the notion of kindergarten until 58 years old, and he had been a teacher for four decades. The notion was a haven and a preparation for children who were about to enter the regimented educational system. The use of guided or structured play was a cornerstone of his kindergarten education because he believed that play was the most significant aspect of development at this time of life. Play served as a mechanism for a child to grow emotionally and to achieve a sense of self-worth. Meanwhile, teachers served to organise materials and a structured environment in which each child, as an individual, could achieve these goals. When Froebel died in 1852, dozens of kindergartens had been created in Germany. Kindergartens began to increase in Europe, and the movement eventually reached and flourished in the United States in the 20th century.

A desert refers to a barren section of land, mainly in arid and semi-arid areas, where there is almost no precipitation, and the environment is hostile for any creature to inhabit. Deserts have been classified in a number of ways, generally combining total precipitation, how many days the rainfall occurs, temperature, humidity, and sometimes additional factors. In some places, deserts have clear boundaries marked by rivers, mountains or other landforms, while in other places, there are no clear-cut borders between desert and other landscape features.

B

In arid areas where there is not any covering of vegetation protecting the land, sand and dust storms will frequently take place. This phenomenon often occurs along the desert margins instead of within the deserts, where there are already no finer materials left. When a steady wind starts to blow, fine particles on the open ground will begin vibrating. As the wind picks up, some of the particles are lifted into the air. When they fall onto the ground, they hit other particles which will then be jerked into the air in their turn, initiating a chain reaction.

C

There has been a tremendous deal of publicity on how severe desertification can be, but the academic circle has never agreed on the causes of desertification. A common misunderstanding is that a shortage of precipitation causes the desertification—even the land in some barren areas will soon recover after the rain falls. In fact, more often than not, human activities are responsible for desertification. It might be true that the explosion in world population, especially in developing countries, is the primary cause of soil degradation and desertification. Since the population has become denser, the cultivation of crops has gone into progressively drier areas. It’s especially possible for these regions to go through periods of severe drought, which explains why crop failures are common. The raising of most crops requires the natural vegetation cover to be removed first; when crop failures occur, extensive tracts of land are devoid of a plant cover and thus susceptible to wind and water erosion. All through the 1990s, dryland areas went through a population growth of 18.5 per cent, mostly in severely impoverished developing countries.

D

Livestock farming in semi-arid areas accelerates the erosion of soil and becomes one of the reasons for advancing desertification. In such areas where the vegetation is dominated by grasses, the breeding of livestock is a major economic activity. Grasses are necessary for anchoring barren topsoil in a dryland area. When a specific field is used to graze an excessive herd, it will experience a loss in vegetation coverage, and the soil will be trampled as well as be pulverised, leaving the topsoil exposed to destructive erosion elements such as winds and unexpected thunderstorms. For centuries, nomads have grazed their flocks and herds to any place where pasture can be found, and oases have offered chances for a more settled way of living. For some nomads, wherever they move to, the desert follows.

E

Trees are of great importance when it comes to maintaining topsoil and slowing down the wind speed. In many Asian countries, firewood is the chief fuel used for cooking and heating, which has caused uncontrolled clear-cutting of forests in dryland ecosystems. When too many trees are cut down, windstorms and dust storms tend to occur.

F

What’s worse, even political conflicts and wars can also contribute to desertification. To escape from the invading enemies, the refugees will move altogether into some of the most vulnerable ecosystems on the planet. They bring along their cultivation traditions, which might not be the right kind of practice for their new settlement.

G

In the 20th century, one of the states of America had a large section of farmland that had turned into desert. Since then, actions have been enforced so that such a phenomenon of desertification will not happen again. To avoid the reoccurring of desertification, people shall find other livelihoods which do not rely on traditional land uses, are not as demanding on local land and natural resource, but can still generate viable income. Such livelihoods include but are not limited to dryland aquaculture for the raising of fish, crustaceans and industrial compounds derived from microalgae, greenhouse agriculture, and activities that are related to tourism. Another way to prevent the reoccurring of desertification is bringing about economic prospects in the city centres of drylands and places outside drylands. Changing the general economic and institutional structures that generate new chances for people to support themselves would alleviate the current pressures accompanying the desertification processes.

H

In nowadays society, new technologies are serving as a method to resolve the problems brought by desertification. Satellites have been utilised to investigate the influence that people and livestock have on our planet Earth. Nevertheless, it doesn’t mean that alternative technologies are not needed to help with the problems and process of desertification.

Every two years, people around the world wait in anticipation as a torch-bearing runner enters the Olympic arena and lights the cauldron. The symbolic lighting of the Olympic flame marks the beginning of another historic Olympic Games. The opening ceremony is the end of a long journey for the Olympic torch. The ancient Greeks revered the power of fire. In Greek mythology, the god Prometheus stole fire from Zeus and gave it to humans. The Greeks held their first Olympic Games in 776 B.C. The Games, held every four years at Olympia, honored Zeus and other Greek gods. A constantly burning flame was a regular fixture throughout Greece. At the start of the Olympic Games, the Greeks would ignite a cauldron of flame upon the altar dedicated to Hera, goddess of birth and marriage.

B

The flame was reintroduced to the Olympics at the 1928 Amsterdam Games. A cauldron was lit, but there was no torch relay. The first Olympic torch relay was at the 1936 Berlin Summer Games and it was not introduced to the Winter Olympics until the 1952 Games. It was lit that year not in Olympia, Greece, but in Norway, which was chosen because it was the birthplace of skiing. But since the 1964 Olympics at Innsbruck, Austria, every Olympic Games – Winter and Summer – has begun with a torch-lighting ceremony in Olympia, Greece, followed by a torch relay to the Olympic stadium.

Designing an Olympic Torch

C

The torch starts out as an idea in the mind of a designer or group of designers. Several design teams submit proposals to the Olympic Committee for the opportunity to create and build the torch. The team that wins the assignment will design a torch that is both aesthetically pleasing and functional. A torch can take a year or two to design and build. And once the torch has been built, it must be tested rigorously in all kinds of weather conditions. The look of the modern Olympic torch originated with John Hench, a Disney artist who designed the torch for the 1960 Winter Olympics in Squaw Valley, California. His design provided the basis for all future torches. Since then, designers have tried to create a torch that represents the host country and the theme for that Olympic Games.

D

The torch must then be replicated … and replicated. It’s not just one torch making the journey to the Olympic stadium; it’s thousands. Anywhere from 10,000 to 15,000 torches are constructed to accommodate the thousands of runners who carry them through each leg of the Olympic relay. Each runner has the opportunity to purchase his torch at the end of his leg of the relay.

Olympic Torch fuel

E

The first torch used in the modern Olympics (the 1936 Berlin Games) was made of a thin steel rod topped with a circular piece from which the flame rose. It was inscribed with a dedication to the runners. The torch must stay lit for the entire length of its journey. It must survive wind, rain, sleet, snow, and a variety of climates (desert, mountain, and ocean). For fuel, early torches burned everything from gunpowder to olive oil. Some torches used a mixture of hexamine (a mixture of formaldehyde and ammonia) and naphthalene (the hydrogen- and carbon-based substance in mothballs) with an igniting liquid. These substances weren’t always the most efficient fuel sources, and they were sometimes dangerous. In the 1956 Games, the final torch in the relay was lit by magnesium and aluminum, burning chunks of which fell from the torch and seared the runner’s arms. The first liquid fuels were introduced at the 1972 Munich Games. Torches since that time have carried liquid fuels – they are stored under pressure as a liquid but burn as a gas to produce a flame. Liquid fuel is safe for the runner and can be stored in a lightweight canister. The torch designed for the 1996 Atlanta Summer Olympics has an aluminum base that houses a small fuel tank. As fuel rises through the handle, it is pushed through a brass valve with thousands of tiny openings. As the fuel squeezes through the small openings, it builds pressure. Once it makes it through the openings, the pressure drops, and the liquid fuel turns into gas for burning. The tiny holes maintain a high pressure in the fuel to keep the flame going through harsh conditions.

F

The 1996 torch was fueled by propylene, which produced a bright flame. But because propylene contains a high level of carbon, it also produced a lot of smoke – not a plus for the environment. In 2000, the creators of the Sydney Olympic torch came up with a more lightweight, inexpensive, and environmentally friendly design. To fuel their torch, they decided on a mixture of 35 percent propane (the gas used to heat home stoves and barbecue grills) and 65 percent butane (cigarette lighter fuel), which ignites a strong flame without making a lot of smoke. Because the propane/butane mixture can be stored as a liquid under relatively light pressure, it can be kept in a lightweight container. It then burns as a gas under normal atmospheric pressure. The liquid fuel is stored in an aluminum canister located about halfway up the torch. If flows up to the top of the torch through a pipe. Before leaving the pipe, the liquid fuel is forced through a tiny hole. Once it moves through the hole, there is a pressure drop, causing the liquid to turn into gas for burning. The torch moves the liquid fuel at a consistent rate to the burner, so the flame always burns with the same intensity. The torch can stay lit for about 15 minutes.

G

The engineers behind both the 1996 and 2000 torches adopted a burner system that utilized a double flame, helping them to stay lit even in erratic winds. The external flame burns slowly and at a lower temperature than the internal flame. This flame is big and bright orange, so it can be seen clearly, but it is unstable in winds. The interior flame burns hotter, producing a blue flame that is small but very stable because its internal location protects it from the wind. It would act like a pilot light, able to relight the external flame should it go out.

H

When the 2002 Olympic Torch, in Salt lake city, the top section was glass, and the Olympic Flame burned within the glass, echoing the 2002 Olympic theme Light the Fire Within. The glass stood for purity, winter, ice, and nature. Also inside the glass was a geometric copper structure which helped hold the flame. The two silver sections also mirrored the blue/ purple colors of the Fire and Ice theme.
